Mid-Southern Bancorp, Inc. Announces Proxy Advisory Firms ISS and Glass Lewis Recommend Stockholders Vote “AGAINST” Stockholder Proposal Recommending the Engagement of an Investment Banking Firm

SALEM, Ind., May 16, 2023 (GLOBE NEWSWIRE) -- Mid-Southern Bancorp, Inc. (the “Company”) (Nasdaq:MSVB), the holding company for Mid-Southern Savings Bank, FSB (the “Bank”), today issued the following letter to the Company’s stockholders in connection with the Company’s annual meeting of stockholders (the “Annual Meeting”):

May 16, 2023

Dear Stockholder:

In connection with the annual meeting of stockholders (the “Annual Meeting”), the Board of Directors of Mid-Southern Bancorp, Inc. (the “Company”) is proud to announce that leading independent proxy advisory firms, Glass Lewis & Co. and Institutional Shareholder Services, Inc., recently recommended that stockholders vote AGAINST the stockholder proposal recommending the engagement of an investment banking firm to sell the Company. We urge you to vote AGAINST the stockholder proposal by signing, dating and returning the proxy card for the Annual Meeting.

The Board of Directors believes that the stockholder proposal is unnecessary and not in the best interests of the Company or its stockholders. We believe that actively seeking a buyer would be a distraction to the Company and may damage our reputation with our clients by creating uncertainty. In addition, due to the current state of volatility in the capital and credit markets and uncertainty with respect to the health of the U.S. banking system, we believe that the current market is an especially inopportune time to explore a sale of the Company.

If you have any questions or need assistance in voting your shares, please contact our proxy solicitation agent Alliance Advisors toll-free at 1-888-490-5076. We appreciate your prompt attention to this matter, and your continued support of and interest in our Company.

Sincerely yours,

Dana J. Dunbar

Chairman of the Board
